How can you think anything else when you see the trailer for “Avengers: Infinity War,” which Marvel released Friday?

Truly, the gang is all here, seems like, not just Iron Man and Captain America and Black Widow and that bunch, but also Black Panther, Ant Man, Doctor Strange and the folks from “Guardians of the Galaxy,” among many, many others. If the movie isn't five hours, how will there be room for everyone?

Does the movie look good? Who knows? This is a trailer. They’re a bane — too misleading, give too much away, etc. — but these movies (along with “Star Wars” films and other blockbusters) get studied by fanboys all along the chain to release, so there’s no avoiding them. They’re treated like mini-releases all on their own.

So what do we learn?

Well, mondo bad guy Thanos is coming to Earth, and not for a Denny’s Grand Slam. “The entire time I knew him, he only ever had one goal — to wipe out half the universe.” So says Gamora (Zoe Saldana) in a serious-minded voiceover. Iron Man (Robert Downey Jr.) seems appropriately concerned, which kicks off a blizzard of quick cuts introducing many (though not all) of the players involved.

The good: Happily it’s not all serious business. In one quick bit Star-Lord (Chris Pratt) is standing in a group of Avengers, evidently just having listened to Iron Man lay out a plan.

The bad: We see snippets of yet another chaotic, incoherent, CGI-heavy Marvel-style climactic battle. How could there not be? Just because you know it’s coming doesn’t mean you have to be happy about it.

The bottom line: IT’S A TRAILER. Cool your jets. And even though we don't see Tom Hiddleston in the trailer (I don't think), just remember the key to quality for all of the “Avengers” films: Lots and lots of Loki.

“Avengers: Infinity War” is scheduled for release on Friday, April 26.
